Pakistani authorties have questioned several students, teachers and administrators at one of two religious schools believed visited by a suspect in the London (search) bombings, intelligence and school officials said Saturday.

Police, intelligence and Interior Ministry officials, meanwhile, vehemently denied reports that arrests had been made in the case.

The intelligence agents, who spoke to The Associated Press on condition of anonymity because of the secretive nature of their work, said agents had been dispatched to the Jamia Manzoorul Islam seminary in central Lahore, one of two religious schools — or madrassas — allegedly visited by 22-year-old bomber Shahzad Tanweer (search) on a trip to Pakistan.

Asad Farooq, a spokesman for the school, acknowledged in an interview with AP that intelligence agents had been around on Saturday, but denied Tanweer had ever been at the school.

"Our hands are clean. We are not involved in any such activities. We are simply running an education facility," Farooq said. "Our doors are open and anyone can visit us and see what goes on here. We have no link with Shahzad Tanweer or any other foreign students at our madrassa."

The same officials denied a report by an international news agency that two people had been arrested in Lahore. Amir Zulfikar (search), operations chief of the Lahore police, also said the report was wrong.

"We have made no arrests in Lahore either today or last night," he said. A senior Interior Ministry official said authorities would put out a statement denying any arrests in Pakistan in connection with the London bombings.
